ROBERT M. BURNS, OF KENILWORT ILLINOIS, ASSIGNOR TO CHAMBER-LIN METALWEATHERSTRIIP COMPANY, OI DET OI'I, MICHIGAN, A CORPORATION OF MICHIGANWEATHER srmr Application filed J'une-22, 1929. Serial No. 372,959

This invention relates to weatherstrips and the object of the inventionis to provide a Weatherstrip for a swinging wood casement or door andarranged to seal the outer face of the door or casement as well as theedge thereof.

A further object of the invention is to provide a spring metal weatherstrip adapted tosea-ltwo faces of the closure member,one seal being asliding contact and the other seal being a pressure contact.

A further object of the invention is to provide a spring metalWeatherstrip bent at a right angle and having two inwardly extendmg gageby the edge and face respectively of the closure member.

These objects and the several novel features of the invention fullydescribed and claimed and the preferredrform'of construction by whichthese 1 objects are attained is shown in the accompanying drawings inwhich-'- Fig. 1 is an elevation of a swinging casement with which theWeatherstrip is used.

Fig. 2 is an enlarged section through the window frame showing theWeatherstrip mounted therein.

Fig. 3 is a similar section showing the swinging casement in relation tothe weatherstrip and window frame.

Fig. 4 is a perspective view of a portion of the Weatherstrip. f

Fig. 5 is a section showing an alternative form of the ,weatherstrip inrelation to the swinging casement and frame.

Fig. 6 is a section showing another-alternative form of the Weatherstripin relationto the window frame.

Fig. 7 is a section showing the swinging casement in operative relationwith the lzrvea'itherstrip and window frame shown in Fig. 8 is a sectionthrough another alternative form of Weatherstrip as utilized with analternative form of window frame.

Fi 9 is a similar view showing the closure memer in relative relationtherewith.

Fig; 10 is a section showing another alternative form of Weatherstrip.

s ring metal flangesadaptedtobeenare hereinafter more- The principle ofoperation throughout the various alternative forms pf Weatherstrip s thesame in that the weatherstrips each seal the "edge and face of'theswinging closure member. In Figs. 2, 3 and 4 the Weatherstrip comprisesa flatspring metal base portion 1 having a flange 2 extending therefromat a right angle and this flange 2' engages against the shoulder 3formed in the window frame. At the outer edge of the base/portion isreturn bentv upon itself to form a portlon through which securing nails4 may be driven and this return bent portion terminates in an angularlyextending spring metal flange 5 which may be provided with a hemmedterminal edge 6 if desired.

The flange 2 is provided with a bead 7 rolled therein from which theflange 8 extends at an angle toward the flange iand this flange 8 may beprovided with; a hbmmed or return bent terminal edge 9 if desired. Asthe swinging casement is swung to the closed position, the edge 10thereof rides in contact with the flange 5 of the Weatherstrip thusdepressing this flange and sealing the case-- mentat the edge while theface 11 of the casement engages the spring metal flange 8 and compressesit as shown in Fig. 3 thus also sealing the face of the casing. By thisarrangement the easement is sealed at two points against the weather.

It "will be noted from Fig. 3 that the head 7. extends to the outside ofthe flange 2. In Fig. 5 an alternative-form is shown in Whlgll a bead 12is formed in the metal on the inside of the flange 2 and a flange 13 isprovided.

extending upwardly therefrom into contact with't-he face of the casing.In this view 1t will be noted that the face of the casing contacts thehead 12 as well as the spring metal flange 13 and thus the face of. theeasement is sealed at two points.

An alternative form of the Weatherstrip is shown in Figs. 6 and 7- inwhich the flange 2 is provided with an enlarged bead llrolled thereinand this bead is provided with an angularly extending spring metalflange 15 which extends intocontact with the face 16 of the windowframe.

When the easement is swung into the frame tween the casing and frame. 1

leakage between the casement and the bead 14 while the easement is alsoadditionally sealed by the spring metal flange 5.

As shown in Figs. 8 and 9 windows and frames are-sometimes made withoffset shoulders which inter-engage as shown'in Fig. 9 when the easementis swung into closed posit-ion in the frame. a Weatherstrip is providedas shown in Fig. 8 having a base portion 1 and return bent flange 5 andthe securing nails 4 and this base portion 1 is provided with a flange17 engaging against the face of the window frame 18 and provided with aretur-n bent portion 3 19 through which additional securing nails 20 aredriven into the window frame 18. The return bent portion 19 extendsoutwardly and is provided with a bead 21 rolled in the outer edgethereof from which a spring metal flange 22extends, as shown in Fig. 8.This bead 21 and flange 22 are ilmllal to the bead 12 and flange 13shown in i 5. FVhen the easement 23 is swung to the .closed position, asshown in Fi 9, the edge of the casement compresses the ange 5 while theface 24 of the easement compresses the flange 22 and engages the head 21thus sealmg the casement at two points on its face and at a single pointon its edge. If desired the head 21 and flange 22 maybe replaced by thehead 7 and the flange 8'shown in Figs. 2, 3 and ff. In this form theWeatherstrip is substantially T'shaped and entirely covers the jointbetween the casement and frame and prevents leakage through the spacebe- In Fig. 10 an alternative form of the weath- For this constructiontion, its utilit and mode of operation, what I claim and esire to secureby Letters Patent of the United States is- 1. In a Weatherstrip, a basemember formed of spring metal and having a flange extending at a rightangle thereto, a bead rolled into the outer edge of the said flange andhaving an integral spring metal flange extending toward the base member,the edge of the base member opposite the right angle flange being returnbent to provide a spring an angle greater than a right angle one to theother with the free edges in adjacent relation.

3. In a weather strip for introduction between a frame and a hingedsash, said frame having a surface parallel with the peripheral edge ofthe sash and a surface parallel wlth the side face of the sash, a springmetal strip having a base consisting of a portion attachable to theframe and fitting each of the said surfaces thereof, the opposite edgesof the strip being return-bent toward the respect1ve base portions andnormally lying at an angle thereto with the free edges in adjacentspaced relation providing respectively for sliding contact with therespective peripheral edge and side face of the sash.

In testimony whereof I sign this specification.

erstrip is shown in which the basemember I i 1 is provided with a returnbent flange 25 and thespring metal flange 5 is'a separate piece and isslipped beneath the return bent flange 25 and the nails 4; are driventhrough the return bent flange 25 and spring metal flange 5 to securethe device to the Window frame. In all other respects .this form is thesame as that shown in Fig. 2.

From the foregoing description it becomes evident that the device isvery simple and efiicient in operation, will provide a double seal forhinged casement and doors,-will rovide a resilient stop for the casementor oor and provides a devlce which accomplishes the objects described.
